Interesting but entirely backwards thinking IMO. The idea that Marvel are copying DC is somewhat backwards, given that Rebirth is DC's attempt to replicate Now! I see zero evidence that Marvel have anything to worry about from DC, as their sales graphs are already back on track and mirroring the direct market. I admit these are early signs, and we need another couple of months of data to be sure, but the figures seem to demonstrate Marvel have regained the somewhat dominant share of the market place that they had before Rebirth.
As for these stories, so far we have only seen two books and they don't seem to be trying to fix anything at all. If anything they are sticking to their plans, but reminding the cynics that none of the current stories are divorced from their original premise, are all exploring similar themes, and were all intended to be finite explorations. You seem to be assuming an awful lot from books we have yet to read, aside from a few pages in a preview.
